To all whom it may concern:

Be it own that l, 5'? .i .fm M. our, a

citizen oi the United Stutes,residing at the same reference be bad tothe mpanying drawings, forming part oi this application2 in Which-Figure l is e top plan view oi my improved motor truck.

l-ligure 2 is a side elevational ,view oi the same, partly in verticelsection.

Figure 3 is a vertical sectional view taken substantially at tbe centeroi the truck, the left hand portion omitting tbe bolster. Fire t is n.die fr u :Matic view illustrate ing te driving connections between theme tor und the wheel eules.

This invention relates to e newand useful provement in ctor truc end isci the type-'own in e companion application died by me ci even dateherewith, Serial Number idbddd.

The object ot my present invention is to construct a motor truck nemeand .251 mount ci cast steel `whereby the motor may be mounted on thetruck frame, to one side ci the center thereof, to operette, throu hsuitable transmission gearing, lcountcrsha extending in `oppositedirections from the trasmfengearing casing to drivin gears on the truckaxles, respectively, w ereby both of said truck axles are directlygeared for positive drive to the motor. To provide space for thel motorand een gear casing, l arrange the truck bolster warts to one side ofthe center of the truck me.

In the particular pe of truck shown, the axle beer are located outsideof the wheels, as usual', but there are no connecting rods or pitmansconnec to the truc wheels es disclosed in the companion applicationaioid. The truck is equipped -with a conventional of internal combustionengine with the usual friction clutch and selective gear shift, wherebyboth axles are positivel and reetly driven. e motor em loye may be orany coercial vg an proies-ably is capable oi generating 2 om three tosix hundrei bfi-wer, dending upon the grades encountered and the load tobe hauled.

in practice, there is usually a truck under each end of the car, andeach of these trucks may be motor-equip ed with control-` ling meanstherefor extending through the platform of the car and into a vestibuleor cab located at the end or ends ci the car. Each car thus becomes aself-contained motor driven unit and may be employed on side, brauch andtap lines, as they are sometimes called, in baulin or delivering freightto the main lines; 'Bourg of standard gauge and having standardequipment, such a motor car can be cou led to a train on the -main linefor a long aul. The motor car, of course, will take care of the shorterhauls,

and by replenishing the liquid fuel, may make hauls of greater or lessdistance.

l have illustrated an internal combustion en 'ne as a iorm of motivepower used, but it 1s obvious that other types of motors could Memployed. ere the road is electrified, electric motors could be used.

ln the drawings, the truck frame is shown as being made of a singlecasting, preferably steel, in which vl. indicates the side members, 2the end members, and 3 the transom members. The side members arepreferably boxshuped in cross-section l(as shown in Figure 3) while theend and transom members are substantially channel shape (see Figure 2),said end and transom members being provided With perforated lugs for theattach- *ment oi the brake rigging, the pull rods of which are indicatedat B, Figure 1.

4 are channel-shaped longitudinally disposed members extending from oneof the end members 2 to one of the transom members 3, said members 4iormin a. support for the motor or en e casing and being preferably morewi ely spaced apart at their inner ends to accommodate the transmissiongear casing, as indicated.

5 indicates the bolster having the usual center bearing 6, said bolsterhaving spring seats 7 near each lend restin upon springs 8 shown inythis insee as e tic s rings. springs 8 rest upon sprang pla 9 w ich inturn is ba c'iljflss-member 10 of su o.. `n, ese supporting lilo@ eFigure 2) co-operete with pins 13 passing through bearings extendingfrom the lower laces ci the transoms 3.

supported driven through shafts 22 leading from the vit transmissiongear casing 23 and extending between bolster 5 and spring plank 9. Gears20, pinions 2l and shalt 22 are preferably encased by housings2ll.

'lhe transmission gear casing is supported upon the inner ends oi'members l and juxtaposed to the engine trame provided with its usualcomplement ot cylinders 26. The

, controlling devices ior the engine are not shown, but these preferablyextend into a cabin or vestibule at the end ot the car, and may bemanipulated in a well known manner. llt will be noted that the motor isdirectly connected to both axles and consequently bears direct drivingrelation thereto. The motor and transmission gearing may have a verticalmovement relative to the axles or vice versa, but as the gear housings2d are pivotally mounted ontheir axles, respectively, they will permitthis lwithout materially disturbing the alinement between the shafts 22and their. driving pinions in the transmission gear casing.

Whatllclaim is: l j

1. 'lhe combination oia truck frame, its wheels and axles, a motormounted on said tramo, a transmission gear casing juxtaposed to saidmotor, and shafts spaced from each other transversely oi the truckextending from said casing in opposite'directions and'geared to saidaxles.

2. rlfhe combination ci a truck frame, its wheels and axles, said trucktrame having longitudinally disposed supporting' members more widelyspaced apart at their inner ends, a motor supported by said Amembers atone end, a' transmission gear casing Laia in opposite directions andgeared to said axles, and casings pivotally mounted on said axles forenclosing said axle gearing and their driving shafts.

3. A motor truck tre comprising side, end and transomy members, andmotor supporting members extending between one or said end members andone of said transom l members, said motor supporting members being morewidely spaced at one `end than at the other. Y

*t A motor truck trame com rising side, end and transom members, perorated lugs on `certain ci saidmemberstior the attachment oit brakebeams, a bolster ,located betweeni said transom membersv and to one sideof the center line of said truclr trame, and longitudinally disposed endymembers and one ot said transom me bers 4 5. .ln a truck, a trame, abolster, a spring plank, wheeledv axles, a motor mounted on said traine,a transmission tor said motor and drive shaiting :trom said transmissionto said axles, a portion of which sliatting passes between said bolsterandv spring planlx. Y,

6. ln a truck, spaced wheeled axles, trame, a bolster between one end otthe said trame` and thel center thereoi, motor mounted on said 'tramebetween the other end oil the trame and the center thereof, transmissioncasing between said meter and bolster and between said axles, driveshatts trom said transmission casing to each ot said axles;

7. ln a truck, a `iframe, wheeled axles, a L

motor positioned over the longitudinal center line of the truck,transmission mechamotor suppcrting members extendingbetween one oie saidi ce f nism for said motor, and drive shafts Jfrom said transmission tosaid axles located on opposite sides of the longitudinal center line` oithe truclr. y
